50 free Hermione Granger trivia questions with answers — literature quiz, new questions added Aug 2026.
Hermione Granger boards the Hogwarts Express in Harry Potter and the Philosopher's Stone having already memorised every textbook, and spends the next seven books proving that information brings power. J. K. Rowling has called her a "borderline genius" and an exaggerated version of her own younger self: bossy on the surface, afraid of failure underneath. Emma Watson played her in all eight films after auditioning eight times, and Noma Dumezweni took the role to the stage in Harry Potter and the Cursed Child. This quiz follows Hermione book by book: the troll, the Polyjuice cat hair, the Time-Turner, SPEW, Dumbledore's Army, the Slug Club and the false memories she gives her parents. It also covers the names Rowling nearly used, the Shakespeare play behind her first name, her otter Patronus, the actress considered before Watson and what the critics and scholars made of her. Fifty questions, four options each, with a short explanation after every answer. Play on your phone or print it for a quiz night.
